Traction control... on or off?

[ducman77]

No worries mate.
No, no need to purchase a Decat.
The fabricator would just fit the high flow cat somewhere along your system by welding 3in flanges to either end of it.
Bread and butter stuff for a decent fabricator.
Some of the bigger companies i.e. Millett, BCS etc. Will sell you a downpipe with a 200 Cel cat already fitted, so that might be even easier?

OK buddy thank yoy for that and thanks for spelling it out to me still farely new to this sort of thing lol is that the method you went with? I shall have a look at those companies now:)

Car sounds great in the video ROH

Did you notice any smelly fumes from the exhaust when you got rid of your cat?

No...well?, when I run race fuel I do. But it's a good smelly

When or if you get the O2 fault codes...I installed an angled O2 spacer, post cat position, similar to this one: https://www.google.com/search?q=angled+o2+spacer&ie=utf-8&oe=utf-8#q=angled+o2+spacer&tbs=vw:l,ss:9&tbm=shop&start=0&spd=8490139264442685798

Aimed forward and up a bit...no codes since doing so

I've contacted a few exhaust fabricators and one company  (pp tuning) will sell me a 200 cell and downpipe for £250 or 100 cell and down pipe for £310. I know 100 cell would obviously be better but seems they are classed as a race cat are they mot passable? anyone know if there is a big difference between the two?

If the diameter of the pipe is the same it's just the cell count per square inch. 200 vs 100. I would stick with 200 personally. Will still pass mot and not be on the limit like a 100 will be.

[Adamt5386]

Yeah I'm pretty sure it's the same size rather than 3 inch or something. right OK then I thought 200 would be the safe option. still better than the standard cat. do you think it would be better to ask for a 3 inch downpipe rather than standard?

[slix]

Sorry was meaning that the 2 downpipes next to eachother (100 and 200) the differences would only be the cell count. It should be 3" and you just get a reducer to join to your current exhaust further down. The flow has slowed down a lot by the time it's reached the centre of the car so joining into your oem exhaust is fine.

[Adamt5386]

no that's fine I was getting a little confused myself lol the quote that they have me wasn't got 3 inch (I'm assuming 2.75?) but I've asked it to be 3 inch downpipe and 200 cell cat which I think he said would be £325? does that seem to cheap to yoy? or is it just because it's not a named product? it will be joining onto my milltek non res cat back

[slix]

You can get a 3" downpipe and 200 cell cat for much cheaper..I got this one below and really impressed with the quality of workmanship and welding.

 Look at this on eBay  http://www.ebay.co.uk/itm/390464426028

[Adamt5386]

oh ok then that's cool. think that price he gave me was fitted as well! has all good reviews those guys that gave me that quote. I've had a few other quotes from other people and they were as much as £800! powervalve I think was 600 and milltek a bit more. Guess you pay for the name a little. I had seen that one on eBay before actually just hadn't seen any reviews on it

Worth noting my super duper fancy pants mega money APR downpipe with 200 cell cat, literally only just scraped through the MOT.

With all this recent talk of downpipes with sport cats throwing the CEL, I thought I'd take my car to a VW dealer for it's MOT, because I knew they'd be a lot stricter on the emissions than Bob's back street bring it round the back fella type place.

To the dealer's credit, they took the car out and drove it hard to get the cat as hot as possible and even then, it just about managed the pass limit of 0.20.  A standard car would be in the region of 0 - 0.01.

Just thought I'd through that out there because some of these sport cats are pure junk in terms of emissions, which, if you can't be bothered to switch the DP over every year and just want to throw the car into any old MOT station, it can be an issue.

[Shoduchi]

In February I'll take my Ed. 30 to the MOT and see what my BCS Powervalve 200 cel sports cat will do. Curious but not expecting any issue.

[pudding]

Maybe we should put a list together of which downpipe / sports cats pass or fail the MOT 

APR = Borderline!

[AJP]

I posted my emissions results with a full Powervalve a few weeks ago. Easy pass. Can't remember the thread but it's here somewhere.

[Shoduchi]

Always good to know that @AJP .
